If you try to use your Mac for Skype you’ll probably want to get a headset microphone some time. Be aware that Macs don’t actually have a microphone input. They have a line in input. This means with most microphones the signal will be too soft. You can get around this problem by getting a USB headset or some type of preamp. Hopefully this little bit of knowledge will save some readers a few hours of time and 3 or 4 trips to Radio Shack. (I speak from experience on this.)
Do you have any specific hardware to recommend?
I’m having reasonable luck with the Griffin iMic and a cheap headset mic from Walmart. I’d like to get a USB solution–or better yet bluetooth, but for some reason I can’t get my Jawbone headset to work the Leopard.
I have a LogicTech USB headset. I love it. Very nice :-)
